Tube plugs are fitted to take out of service faulty tubes so that a warm exchanger or chiller can operate more efficiently. As a general rule, a vessel has to be retubed if 10% or less of its tubes have been blocked. At both ends of the pressure vessel, tubes must be plugged. Installing a plug that is similar to or made of a material that is appropriate for the tube and tube sheet is a good idea. To release back pressure, use a one-revolution tube reaper to puncture the leaking tube. To keep the tube plugs in place permanently, some contractors weld them to the tube sheet after they have been put.
